GM bulletin 15-00-89-004F
What it saysThis service bulletin provides technicians with updated information to help identify the differences between what is considered a fluid leak, and what is considered fluid seepage. NHTSA’s full summary ↓
GM filed this with NHTSA as a service bulletin dated Aug 7, 2023, received Sep 8, 2023, about the suspension. It names 424 model years across Chevrolet, GMC, Buick and Cadillac (2016–2024). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

What owners reported
Source: NHTSA complaint databaseOwners of the 340 model years this bulletin names have filed 41,237 complaints with NHTSA since 2015. 23,612 of them name Engine, Power Train, Steering — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
On the 2016 Chevrolet Malibu, the 172 owners who gave an odometer reading for Engine reported it at a median of 53,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

Without any warning, I felt and heard a loud thump through the steering wheel as I approached turn 3 from no-name, I had very little steering ability that required heavy handed input on the steering wheel…

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions
Source: NHTSA, 49 CFR 579.5Is GM 15-00-89-004F a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the 15-00-89-004F repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.
Which vehicles does 15-00-89-004F cover?
The manufacturer filed it against 424 model years across 4 brands (Chevrolet, GMC, Buick and Cadillac): 2019 Buick Cascada, 2018 Buick Cascada, 2017 Buick Cascada, 2016 Buick Cascada, 2024 Buick Enclave, 2023 Buick Enclave and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
